I'm trying to figure out if something is wrong with the iphone5 I have or if it's AT&T. In Hawaii, AT&T switched alot over to LTE pretty much on the day I got my new iPhone5. In areas that I know I could make calls on the 4s, people are now telling me my voice is breaking up on the 5. I also noticed that my signal bars are worse than my old phone. Taking it for granted for the moment that the iPhone5 is supposed to have better reception than my old 4s, whats causing the signal change so much? Is the signal bars showing the 4g/LTE signal strength or cellular voice signal? Or if LTE causes interference for voice calls. Since I had my number swapped to the 5, I can't have both phones on to see a direct comparison.
